“The most basic sort of CPU emulator is an interpreter it one by one steps through the instructions, parses each one, and calls the appropriate function for that instruction,” she wrote. Depending on the instruction, this can take from 2x to 100x clock cycles, which explains why you need more than a 486MHz CPU to emulate a GameCube.”įiora’s broke down the process of CPU emulation in more detail. This is why emulation can be so demanding, as Dolphin’s FAQ concisely explains: “when emulating, every basic instruction a game runs needs to be translated to something a PC can execute. Emulating those consoles means converting PowerPC instructions into x86 instructions. The GameCube and Wii both run on IBM’s PowerPC architecture, which uses a different instruction set than the x86 processors that virtually all PCs run on. On Dolphin, Fiora has primarily contributed to the emulator’s CPU core. She started to learn more about programming. And, in the process, grew curious about how emulators work. So she found a way to play it on her computer. She wanted to play Pokemon, but her parents wouldn’t buy her a Game Boy. Fittingly, she owes her career to another emulator called NO$GBA she discovered as a 10-year-old.
Don't do it.įiora is a programmer by day, and contributes to Dolphin on-and-off in her spare time. Ripping your own Wii/GameCube discs is legal, but downloading them is definitely not. For its most accurate audio emulation, Dolphin does require a DSP (digital signal processor) dumped from a Wii downloading that is illegal, but dumping it from your own modded Wii is perfectly legal.

It’s written by programmers like Fiora, and none of that code belongs to Nintendo. The code of the emulator itself is completely legal. If you don’t closely follow the emulation scene, you may wonder why Nintendo hasn’t shut down the Dolphin project.
